ERROR: Subscripting a table using linear indexing (one subscript) or multidimensional indexing (three or more subscripts) is not supported. Use a row subscript and a variable subscript.

Hello experts. I am doing a coding for two tables to find the common factor for a new table. Undamaged table have 269 datas whereas damaged table have 317 datas. I want MATLAB to find the same X Location (column 2) and extract to new table. Below are the coding. However i got error, kindly help to resolve my problem.

% load tables (damaged & undamaged)

x_undamaged = undamaged(:,2);

x_damaged = damaged(:,2);

deforamtion_damaged = damaged(:,5);

deforamtion_undamaged = undamaged(:,5);

%To compare x nodes and extract corresponding deformation for the node

i=1

j=1

for i=1:317

if x_damaged(i) == x_undamaged(i)

new(j,1)= x_damaged(i);

new(j,2)= deformation_damaged(i);

new(j,3) = deformation_undamaged(i);

i=i+1;

j=j+1

else

i=i+1

end

end

New coding below since previously got typos.

x_undamaged = undamaged(:,2);

x_damaged = damaged(:,2);

deforamtion_damaged = damaged(:,5);

deforamtion_undamaged = undamaged(:,5);

i=1

j=1

for i=1:317

if x_damaged(i) == x_undamaged(i)

new(j,1)= x_damaged(i);

new(j,2)= deforamtion_damaged(i);

new(j,3) = deforamtion_undamaged(i);

i=i+1;

j=j+1

else

i=i+1

end

end

i =

1

j =

1

When you do x_damaged = damaged(:,2) it will generate a table with 1 variable. Hence when you try to index into x_damaged later on as x_damaged(i), you get the error, since you need 2 indices to subscript into a table. It looks like you just want to extract that vector. So you can use brace indexing for that

x_damaged = damaged{:,2}

After this the code should work fine.
